About Compton Wavelength Calculator

The Compton wavelength characterizes quantum behavior at short distances and appears in Compton scattering.

Frequently Asked Questions

Is relativistic mass used?

No. Use the particle rest mass in kilograms.

How is this different from de Broglie wavelength?

Compton uses rest mass only; de Broglie depends on momentum.
